Mine's the same. Sound started working a couple of weeks ago with L3's guidance, but after some reboots no more sound. Currently on mine the soundtest on 0,7 works but no sound when trying to play something on my media drive.Doing a lot of scratching around to try and find how it all fits together. Doing the change in webadmin didn't help but not sure that I have undone all the changes.

Add these 2 lines to /etc/modprobe.d/alsa-base.confoptions snd-hda-intel model=autooptions snd-hda-intel enable_msi=0 index=-2hash one out and do the following:reboot, and run sudo aplay -lCheck that your nvidia is at card 0, then test with speakertestIf no sound go back to alsa-base.conf. remove hash from line and hash out the other line.reboot, and run sudo aplay -l, recheck and speakertest

I would appreciate it if people would try it out and let me know how it works for them. I am specifically curious about whether or not the change is necessary to the template file, I don't think it is. I am also very curious if the last addition to the /usr/pluto/bin/LaunchOrbiter.sh script works to persist through reboots.

If it does not work, try:aplay -Dplughw:0,7 /usr/share/sounds/pop.wavwhere 7 is your device #

You might hear a small cartoonish pop when orbiter loads lol... but the test is to play a file and see that you have audio.
